Tidying methods for lists / returned values that are not S3 objects

Broom tidies a number of lists that are effectively S3 objects without
a class attribute. For example, stats::optim(), svd() and
akima::interp() produce consistent output, but because they do not
have a class attribute, they cannot be handled by S3 dispatch.

Arguments

x

A list, potentially representing an object that can be tidied.

...

Additionally arguments passed to the tidying function.

Details

These functions look at the elements of a list and determine if there is
an appropriate tidying method to apply to the list. Those tidiers are
themselves are implemented as functions of the form tidy_<function>
or glance_<function> and are not exported (but they are documented!).
